Nodes, ways and relations use the same overlapping id space. spaces, and ids are only unique for a given element type. In other words, it is possible that data contains both a node with the node id 4242 and a completely unrelated way with the way id 4242. For this reason, it is not a good idea to make the node's id the same as the way it was converted from - there might already be a node using this id.
